Reddit mentions of RiverMaps Colorado River in The Grand Canyon Map - 4th E

Thanks very much!

>What section of the Salmon have you run?

I've actually forgotten! It was 10 years ago for me... I think it was the section with Buckskin Bill's "Castle"...?

> far bigger water ...

Yes, my biggest fear is assessing what exactly an 18'er can punch through and what it can't... big water will obviously change the threshhold!

>What month are you going?

Mid April. From googling folk seem very split on drysuits!

EDIT: I asked another chap this, but will cut/paste one last question if that's OK: do you have book suggestions? I was looking at getting:

• Belknap's Waterproof Grand Canyon River Guide All New Expanded Edition
  
• Colorado River in The Grand Canyon Map - 4th E-RiverMaps
  
• Day Hikes from the River: A Guide to Hikes from Camps Along the Colorado River in Grand Canyon
  
  ... but wasn't sure if the two maps were both necessary...? What'd you take?
